🙋♀️ About Me
I am a third-year Ph.D. candidate in the School of Computing and Data Science (HKU-CDS) at the University of Hong Kong (HKU), advised by Prof. Reynold Cheng.
My research focuses on AI-native data systems and reusable intelligence for agent systems, including query processing over learned and structured relationships, graph hypothesis testing, and agent orchestration with memory retrieval.
I collaborate with Prof. Sihem Amer-Yahia (CNRS, France) and Prof. Laks V.S. Lakshmanan (UBC). I expect to graduate in August 2027. Feel free to reach out via email.

📝 Publications
My publications focus on reliable querying and decision-making, spanning from different types of resource constraints, including limited data access, imperfect data representations, and expensive computation.
On Efficient Approximate Aggregate Nearest Neighbor Queries over Learned Representations
Carrie Wang, Sihem Amer-Yahia, Laks V. S. Lakshmanan, Reynold Cheng
Introduces Aggregate Queries over Nearest Neighbors (AQNNs) and a framework, SPRinT, for cost-efficient aggregate querying over neighborhoods induced by learned representations.
A Sampling-based Framework for Hypothesis Testing on Large Attributed Graphs
Carrie Wang, Chrysanthi Kosyfaki, Sihem Amer-Yahia, Reynold Cheng
Formulates hypothesis testing over attributed graphs as a statistical query processing problem and develops a framework for it and a hypothesis-aware graph sampler PHASE.
